Initially the ship should be equipped with Vorlon Bio-Armor but this plan was abandoned after the attack on Earth. The Drakh poisoned the Earth atmosphere with a deadly virus and so the new mission of the Excalibur was to find a cure before the people on Earth would die. At present it is unclear whether the planned 800 Victory Destroyer would ever be build. Many resources of the Interstellar Alliance are now focused on finding a cure against the virus.

In naval terminology, a destroyer is a fast maneuverable long-endurance warship intended to escort larger vessels in a fleet, convoy or battle group and defend them against smaller powerful short-range attackers. They were originally developed in the late 19th century as a defence against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBD) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats." Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War.
